Thank you for your feedback! Left a comment on your video as well (hope it comes through - been having some problems with commenting for some reason).
It was my intention to tweak the amount of customers & fish to put the player in an uneasy position. Nice work with the puzzle as well! I realise it wasn't clear, but the box was supposed to be something the player would chip away at from day to day (the information within was written thinking the majority of people would read it after the meeting).
As for the story, it was meant to be a mystery at first that slowly resolved as you play. I wanted players to respond with "goal? what is my goal?" and wonder about the fisherman & his son until things fell into place, but I can see how the mayor's final visit is a little anticlimactic for that part of the story. I think there's a horror to the way a massive, harrowing realisation could come to someone not through an extreme moment, but passively sneaking up on them. Although, that might not have been the right fit.
I'm surprised you want to know more about the town! I spent months planning the complexities of the story, and thought that if I added anymore it might seem a bit overwhelming. There should be enough detail hidden in the game so that you can solve the mystery of the fish & what's going on, but I kept background information to a minimum. (AlphaBetaGamer's video has a few comments and there are some real detectives in there if you wanna browse through people's theories!)
I tried an ambiguous ending this time, hoping that the feeling of being left in the dark after the normal ending would serve as motivation for the secret one. I'll consider going back to making both have some degree of satisfaction in the future.
Unfortunately there seemed to be a visual bug (not impacting gameplay) for the UI on your playthrough. My guess is the game window was beyond the vertical limits of your monitor? Sorry about that. It looked like it resolved itself at 50:14. Also my bad with the exiting the game, it should say "hold Escape to quit".
Thank you playing!
